ok curiosity wants to know. if you have a black 100 grit file and a zebra 100/180 grit file, if they are both 100/180 grit why do they feel and work differently? which is better to prep the nail? whic grit do you prefer for the prep of the natural nail? i know some use 180 some use 100...
was thinking about another post and I use the 180 zebra. maybe i need a harsher grit? i'm terrified of over filing the nail plate.
